maximum length of username/password for “action 1.0 mail server” TAC 638645443

[emmherna]

Hi Team,

Hope all is welll,

I have a customer with the below problem:

I've been trying to get the event manager to email through an external password protected mail server. Unfortunately I haven't been able to get that to work. The system works fine with an internal (no password) server.

I used this format for the server address but I can't get it to send an email.

username:password@host

event manager environment _email_server mailuser:mailpassword@XX.XX.XX.XX
event manager environment _email_to networkteam@company.com
event manager environment _email_from Mailrouter@company.com

 action 4.0 mail server "$_email_server" to "$_email_to" from "$_email_from" subject "Router is down" body "$_cli_result" source-interface GigabitEthernet0/0

Testing to the external mail server is fine but I'm still unable to email from this event manager.

Customer would like for you to please elaborate on the "action mail" command of EEM specifically the 'server' attribute: 

http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/eem/command/eem-cr-book/eem-cr-a1.html#wp1625622655

Specifies the e-mail server to be used for forwarding the e-mail. The e-mail server address can be any one of the following template formats:

username:password@host

username@host

host

They would like to know if there are there any limitations to username or password length and complexity?

Your help on this matter is highly appreciated.

I don't know the answer.

I couple of obvious things.  The username and password wont be able to contains the delimiters, so these two characters can't be used:

:@

I'm also thinking this character would probably not work:

"

As for the length, generate a very large string and configure it on a test router.  Do a packet capture using Wireshark, and see how much of it makes it into the packet.

This could be very version dependent as well.

Yep, '@' will not work in applets (within a username).  You'll need to convert to a Tcl script to be able to use this.  In terms of length, there isn't a hardcoded limit there.
